Electric, Gas/Oil (or Fossil Forced Air)
Note: This ISU is displayed only if ISU 200 is set to Heat Pump AND if ISU 221 Aux/E heat
stages = 1 AND if ISU 253 is set to run AUX/E heat separately.
Thermostat, External (Fossil Fuel Kit Controls Backup Heat)
Note: This ISU is displayed only if ISU 200 is set to Heat Pump AND if ISU 221 Aux/E heat
stages = 1, AND if ISU 256 is set to Gas/Oil.
0 = Manual
1 = Automatic
Note: Thermostat can automatically control both heating and cooling to maintain the desired
indoor temperature. To be able to select "automatic" system mode on thermostat home screen,
turn this feature ON. Turn OFF if you want to control heating or cooling manually.
0 °F to 5 °F or 0.0 °C to 2.5 °C
Note: Differential is the minimum number of degrees rise or fall required during off cycle to
switch from the last active mode (heat or cool) to the opposite mode when the thermostat
is in auto-changeover. Differential is NOT deadband. The deadband temperature between
when heating (or cooling) cycles on and cycles off to maintain setpoint is not adjustable. This
thermostat uses an algorithm that fixes deadband at 0 °F.
Yes, No
Note: This ISU is only displayed when the thermostat is set to 2 cool stages. When set to YES,
this feature keeps the higher stage of the cooling equipment running until the desired setpoint
is reached.
Yes, No
Note: This ISU is only displayed when the thermostat is set to 2 or more heat stages. When set
to YES, this feature keeps the higher stage of the heating equipment running until the desired
setpoint is reached.
0 = Comfort; 2 °F to 15 °F from setpoint (in 1 °F increments) or 1.0 °C to 7.5 °C from
setpoint (in 0.5 °C increments)
Note: Aux heat droop can be set on heat pump systems with an auxiliary heat stage. The
Comfort setting is NOT available for Dual Fuel systems. Default setting is 0 °F (Comfort) for
Electric while 2 °F for Gas/Oil. The indoor temperature must drop to the selected droop setting
before the thermostat will turn Aux Heat on. For example, if Aux Heat is set to 2 °F (1.0 °C),
the indoor temperature must be 2 ° F (1.0 ° C) away from the setpoint before Aux Heat turns
on. When set to Comfort, the thermostat will use Aux Heat as needed to keep the indoor
temperature within 1 °F (0.5 ° C) degree of the setpoint.
Off, 30, 45, 60, 75, 90 minutes
2, 3, 4, 5, 6, 8, 10, 12, 14, 16 hours
Note: The Auxiliary Heat Upstage Timer starts when the highest stage of the previous heating
equipment type turns on. Auxiliary heat will be used (if needed) when the timer expires. This ISU
is only displayed when ISU 340 (AUX Heat Droop) is set to 2 °F or higher.
Off, 5 °F to 60 °F (in 5 °F increments) or 15.0 °C to 15.5 °C (in 2.5 °C or 3.0 °C increments)
Note: Compressor Lockout requires an outdoor temperature. Set Compressor Lockout to the
temperature below which it is inefficient to run the heat pump. When outside temperature is
below this setting, thermostat will lockout the heat pump and run Aux Heat only. This ISU is only
displayed if ISU 130 = Wired, ISU 200 is set to Heat Pump, ISU 221 Aux/E stages = 1. Default
is 40 °F if ISU 205 Heating Equipment is Air to Air Heat Pump and ISU 255 Aux Heat Type is
Gas/Oil. Default is Off if ISU 205 Heating Equipment is Air to Air Heat Pump and ISU 255 Aux
Heat Type is Electric. Default is Off if ISU 205 Heating Equipment is Geothermal. Compressor
Lockout is optional for any type of heat pump (Air to Air Heat Pump, Geothermal Heat Pump).
Off, 5 °F to 65 °F (in 5 °F increments) or
-15.0 °C to 18.5 °C (in 2.5 °C or 3.0 °C increments)
Note: Aux Heat Lockout requires an outdoor temperature. Set Aux Heat Lockout to optimize
energy bills and to not allow to run the more expensive Aux Heat source above certain outdoor
temperature limit. This ISU is only displayed if ISU 130 = Wired, ISU 200 is set to Heat Pump,
ISU 221 Aux/E stages = 1.
1 - 6 CPH (3 CPH)
Note: This ISU is only displayed when Cool /Compressor Stages is set to 1 or more stages. Cycle
rate limits the maximum number of times the system can cycle in a 1 hour period measured
at a 50% load. For example, when set to 3 CPH, at a 50% load, the most the system will cycle
is 3 times per hour (10 minutes on, 10 minutes off). The system cycles less often when load
conditions are less than or greater than a 50% load.
